So far this year four cyclist have been killed on London's roads.
That's compared to 14 deaths in total last year - a figure which represented a 13% drop on the year before.
There were also 657 serious injuries last year, though no comparable figure has yet been compiled for this year to date.
20-year-old Boris Bike user Philippine Degerin-Ricard was killed in a collision with a lorry in Whitechapel last weekend.
Now campaigners say the section of the cycle superhighway on Whitechapel Road where she died needs urgent improvement to make it safe.
Whitechapel Road facts:
- 1,100 lorries use the route everyday.
- In all 30,000 vehicles travel on Whitechapel Road everyday.
- 600 cyclists pass through every hour.
These figures are from the London Cycling Campaign.
There have been new calls for urgent action to improve one of east London's main cycling routes, following the death of a 20-year-old student last weekend - the first to be killed on a Boris bike.
Protesters from the London Cycling Campaign are riding from Tower Hill to Aldgate tonight to highlight their fears that Superhighway 2 is too dangerous.
